 In [changeset:"48072" 48072]:
 {{{
 #!CommitTicketReference repository="" revision="48072"
 Sitemaps: Add XML sitemaps functionality to WordPress.

 While web crawlers are able to discover pages from links within the site
 and from other sites, XML sitemaps supplement this approach by allowing
 crawlers to quickly and comprehensively identify all URLs included in the
 sitemap and learn other signals about those URLs using the associated
 metadata.

 See https://make.wordpress.org/core/2020/06/10/merge-announcement-
 extensible-core-sitemaps/ for more details.

 This feature exposes the sitemap index via `/wp-sitemap.xml` and exposes a
 variety of new filters and hooks for developers to modify the behavior.
 Users can disable sitemaps completely by turning off search engine
 visibility in WordPress admin.

 This change also introduces a new `esc_xml()` function to escape strings
 for output in XML, as well as XML support to
 `wp_kses_normalize_entities()`.
